The Coral Galaxy!

Well, this is a picture of it.

Now, first remember about the redshift space.

Virgo cluster, but most of them are tiny dwarfs that you have difficulty actually pointing out.

And those smudges we see in the night sky?

There is one important distinction though, the early type galaxies, ellipticals and S0s tend to concentrate in clusters more than in general field and there is relatively few spiral galaxies in clusters.

On the other side is Perseus Pisces

And this is an example of a very, actually, famous cluster, the Coma cluster.

So, let me give you the two examples.

Milky Way and Andromeda are the two dominant galaxies in the group and there is a large number of their dwarf galaxy satellites.

This plot is centered on a local group of galaxies, but really, the center of the Local Supercluster is at Virgo.

Most of them have super massive black holes in the centers.

But the dominant component, of course, is the dark matter.

And things may acutally go even beyond that.

The Andromeda Galaxy is my home.

Think of DNA, cells, galaxies, fruits,

This was noted as an elegant structure in the sky and that we are kind of in its plane.

A different way to measure that, would be from the x ray gas they contain.

So for now, let's turn to the evidence for dark matter.

So, this is what Toomre and Toomre saw. And in fact this explained many puzzling observations.

And here's a beautiful picture of the Andromeda Nebula, which is our closest, largest spiral galaxy to the Milky Way.

When we look out into space, we see stars and galaxies.

If you can map all of the distorted images, you can, in principle, reconstruct the distribution of mass that led to the

The universe is really big.

So if you take a picture of what's going on, it's 10 years ago.

Now we're going to fly through it at warp a million.

And here is a blatant example of dust in a elliptical galaxies.

But before we get into that subject proper, we have to introduce another concept.

What about the other Jedi spread across the galaxy?

We now call them galaxies.

We don't live in the center of the solar system, we don't live in the center of the galaxy and our galaxy's not in the center of the cluster.

These are unknown maps of the neutral hydrogen.
